Right, and indeed someone may decide to plug in something that isn't a WiFi device at all but some other SDIO attached device with totally different uses for those GPIOs. Really these boards are an example of the sort of thing I was talking about with modular reference systems, though a simpler case as given what's brought out you probably can just do something like list all the options that are there and allow hotplug to sort things out. -------------- next part -------------- A non-text attachment was scrubbed...
